???
im not quite sure what you have done but linux has a built in boot menu ?
unless you installed windows on one hardrive removed it installed linux on the other then put them both in ?
you can get a boot manager i used vista boot pro which i actually used on XP to recover a vista partition but im sure it would work with XP and Linux just google it.
( i think acronis has 1 aswell ? google again)
with vista boot pro you just click add new operating system then select a name and select a partition that it boots from ..... simple
